Atomic Displacement Relationship to Curie Temperature and Spontaneous Polarization in Displacive Ferroelectrics
TL;DR: In this paper, a least square fit was performed on displacive ferroelectrics in which atomic positions have been determined and it was shown that a fundamental relationship exists between the Curie temperature and the displacement of certain atoms from their higher-temperature symmetry positions.

Dielectric Properties of Solid Solutions of BiFeO3 with Pb(Ti, Zr)O3 at High Temperature and High Frequency
TL;DR: In this article, the dielectric constants of the materials were determined at a frequency of 0.53 GHz and at temperatures up to 800°C, and the results leave little doubt that BiFeO3 is ferroelectric or antiferroelectric.
